Corbin Russwin 606K76 BL 626 – Frequently Asked Questions

1) What mortise cylinder lengths does the Corbin Russwin 606K76 plug come in?
The 606K76 plug is offered in four mortise lengths: 2-1/4, 2-1/2, 2-3/4 and 3 inches. Match the length to the cylinder housing already in the mortise lock, since the plug has to run the full body length of the cylinder it serves. Each length is available in 606 satin brass or 626 satin chrome.
2) Will the 606K76 BL plug work in my existing key system?
Only if your system runs the Corbin Russwin BL keyway. The plug is factory cut for the BL keyway in a 7-pin Individual X Class configuration, so keys from a different keyway or a 6-pin stack will not enter or operate it. If your facility is keyed on another Corbin Russwin keyway, order that keyway's plug instead.
3) If I need a complete mortise cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 606K76?
The Corbin Russwin 606K76 is a 7-pin cylinder plug for servicing an existing mortise cylinder housing, not a complete cylinder. If the whole cylinder has to be replaced, a full mortise cylinder such as the Detex MC65, a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, or the Adams Rite 4036 five-pin mortise cylinder covers that. Those ship as assembled cylinders; the 606K76 gives you only the plug when the housing stays in the door.
4) Can I use a BEST interchangeable core in place of the Corbin Russwin 606K76 plug?
No. The 606K76 is a plug keyed to the Corbin Russwin BL keyway that drops into a Corbin Russwin mortise cylinder housing. BEST interchangeable cores such as the 1CB 150 Series or the 1CDF 7-pin drill-resistant core are figure-eight cores that require a BEST interchangeable-core housing, and the BEST 1C5 is a standard 5-pin core. They are a different key control platform, so the housing has to match the core family you choose.
5) What do I order if the opening takes a rim exit device instead of a mortise lock?
The 606K76 plug is built for mortise lock cylinders, so it will not serve a rim device. For rim applications the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam; the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Match the cam orientation to the device you are working on.
6) Why choose a 7-pin plug over a 6-pin for a commercial building?
Seven pin chambers give more key differs and a deeper tumbler stack, which matters when you are running a master key hierarchy across many doors and need pick resistance. The Individual X Class designation on the 606K76 is part of Corbin Russwin's key control structure. Six-pin commercial cylinders, like the Detex MC65 in Schlage C keyway, are common but sit in a different key system entirely and will not interchange with a BL plug.
7) Can I use this plug to rekey a mortise lock without replacing the whole lock?
That is exactly the case for it. Swapping the plug lets you change key control on a mortise cylinder while leaving the lock body, trim and housing in place, which is the cheapest way to handle a tenant turnover or a lost-key event across a run of doors.
8) Is this a rim cylinder part or a mortise part?
Mortise. The 606K76 plug is built for threaded mortise cylinder bodies used in mortise lock cases. For a rim application on an exit device you would want a rim cylinder instead, such as the Schlage 20-021 with vertical tailpiece cam or the 20-022 with horizontal cam.
9) We want interchangeable cores instead of pinned plugs. What is the alternative?
A plug swap means pulling and repinning the cylinder. If your goal is to rekey a door in seconds with a control key, move to an interchangeable core platform instead: the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core in the 150 Series, and the BEST 1C is the standard 5-pin core. Schlage's 20-057 is a 6-pin full size interchangeable core rim cylinder. Those are separate key systems from Corbin Russwin BL, so it is a facility-wide decision, not a single-door one.
10) I need a cylinder for a key-in-lever or key-in-knob lockset, not a mortise lock. What are my options?
The Corbin Russwin 606K76 plug fits mortise cylinder housings only. For key-in-knob and key-in-lever locksets, Kaba Ilco offers the 1539 Series universal key-in-knob/lever cylinder and the 1579 Series knob and lever cylinder for Sargent locks, and the 1599 is a key-in-knob replacement cylinder. Falcon's A23161-05 G is a key-in-lever cylinder in the RU/T Series 6-pin G keyway, keyed different with two cut keys.
11) Is a cylinder pull like the Adams Rite 4025 an alternative to the Corbin Russwin 606K76?
They do different jobs. The 606K76 is a keyed 7-pin plug that goes inside a Corbin Russwin mortise cylinder. The Adams Rite 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws, both for use with the Adams Rite MS1847 deadlock/deadlatch, and the 4026 is the five pin tumbler pull for the 5017 wood door deadlock/deadlatch. Those are door pulls with an integral cylinder for narrow stile and wood door deadlocks, not a service part for a mortise housing.
12) For a deadbolt cylinder replacement on a residential-style handleset, what compares to the Corbin Russwin 606K76?
The 606K76 is a commercial mortise cylinder plug, so deadbolt and handleset work calls for a different part. Medeco offers the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 5-pin rim lazy motion cylinder with Emtek tailpiece, and the 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Kaba Ilco's 1549 Series is a key-in-deadbolt cylinder.
13) If I want to standardize a facility on interchangeable cores instead of keeping plugs on the shelf, what would I move to?
The Corbin Russwin 606K76 is a component-level replacement plug that lets you service a mortise cylinder without changing the housing. If you would rather swap keying at the core, full size interchangeable core options include the Schlage 20-057-C FSIC core in the C keyway with a 643E aged bronze finish, and the BEST 1CB 150 Series interchangeable core. That approach changes the housings in the doors, whereas the 606K76 keeps the existing Corbin Russwin mortise cylinders in service.
14) Which finish should I order to match my other Corbin Russwin hardware?
Two finishes are offered: 606 satin brass and 626 satin chrome. 626 is the usual commercial standard and pairs with satin chrome levers and exit trim; 606 is for brass-finished openings. Only the exposed face of the plug shows, so match it to the cylinder ring and lock trim rather than the door.
15) Is the 606K76 suitable for apartments and residential doors?
It is classed as commercial hardware and belongs on commercial mortise locks in offices, schools, healthcare, government buildings and multi-tenant properties. A residential deadbolt or knob lock takes a different cylinder entirely, closer to the Kaba Ilco 1549 key-in-deadbolt or 1599 key-in-knob replacement cylinders.
16) What is the difference between the Corbin Russwin 606K76 plug and a dummy cylinder like the BEST 12E?
The 606K76 is a working 7-pin plug keyed to the BL keyway that carries the key control for a Corbin Russwin mortise cylinder. The BEST 12E Series dummy rim cylinder, 1-5/32 inch diameter, is a non-keyed filler used where the opening needs the look of a cylinder without an operating key. Use the 606K76 where the cylinder actually has to be keyed and operated.
